Usage
Checking Metrics
The following example checks that the count of running processes is between 150 and 300 * a warning message will be triggered if the count is below 150 or above 300 * a critical message will be triggered if the count is below 100 or above 350
check-dcos-metrics.rb -u 'http://127.0.0.1:61001/system/v1/metrics/v0/node' -m 'process.count' -w 150 -c 100 -W 300 -C 350
In some cases the metric name is not unique but you can filter metrics by tags using the --filter option followed by TAG_NAME:TAG_VALUE
You can also check deltas, if you pass the -d option the plugin will keep the previous value in a daybreak db and compare the new value against it.
check-dcos-metrics.rb -m 'network.in.errors' -d -f interface:docker0 -C 2 -W 1
Run check-dcos-me.rb -h for all the options.
Check configuration example:
This is an example how to use this plugin to ship metrics to InfluxDB using the sensu-extensions-influxdb extension:
{
"checks": {
"dcos-host-metrics": {
"type": "metric",
"command": "/opt/sensu/embedded/bin/metrics-dcos-host.rb",
"influxdb": {
"templates": {
"dcos\\..*\\.filesystem\\.": "source.type.measurement.field2.nil.nil.path*",
"dcos\\..*\\.network\\.": "source.type.measurement.field2.nil.nil.interface*",
"dcos\\.": "source.type.measurement.field*"
},
"tags": {
"group": "node"
}
}
}
}
Host Health Check
The check-dcos-ping.rb will return OK if the host reports itself as heathy or CRITICAL otherwize
check-dcos-ping.rb -h 'http://127.0.0.1:61001/system/v1/metrics/v0/ping'
